PRINTING MECHANISM FOR PAPER-BOX MACHINES.

SPECIFICATION forming part of Letters Patent No. 357,553, dated February 8, 1887.

7 Application filed January 8, 1885. Serial No. 152,303. (No model.)

To all whom it ntay concern.-

Be it known that I, HENRY P. FIsKE, of Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain Improvements in Printing Mechanism for Paper-Box Machines, of which the following is a specification.

Thisinvention relates to machines for printing a continuous web of paper and cutting it up into box-blanks ready to be folded into printed boxes; and it consists in an improved printing mechanism adapted' to co-operate with the feeding and cutting mechanism hereinafter described.

Figures 1 and 2 represent in side elevation a machine embodying my improvement, the views illustrating opposite sides of the machine. Fig. 3 is a top view; Figs. 4 and 5, views of details, to be hereinafter referred to; Fig. 6, an end view, and Fig. 7 a longitudinal section.

The same letters of reference indicate the same parts in all the figures.

In the drawings, or represents the general supporting-frame of the machine, provided at one end with the printing mechanism and at the other end with the cutting mechanism. Said frame is preferably inclined, the printing mechanism being arranged at the upper and the cutting mechanism at the lower end of the incline, so that the printed blanks when completed will slide from the machineby gravitation.

The printing mechanism is composed of a platen, 1), arranged above the web of paper to be printed, a reciprocating bed, 0, arranged below the web of paper and caused to alternately approach and recede from the webinking mechanism, whereby the type on the bed is inked while it is withdrawn from the web, and paper-feeding mechanism, whereby the web of paper is moved forward after each impression by the type.

The cutting mechanism consists of a fixed bed or die-block, 02, over which the printed web passes, and a reciprocating cutting-die, e, which is operated so as to cut at the same moment that the bed is printing, the cutting-die being above the web,while the type-bed is below.

The platen b is pivoted to the end of a central screw, 9, working in a tapped socket in a fixed plate, a, on the frame a, the connection between said platen and screw being effected bya ball-and-socket joint, f, or equivalent means, as best shown in Fig. 7, so that the platen can oscillate in any direction on said screw, and can therefore adjust itself to the surface of the bed when the latter is raised, so that the bed will bear evenly against all parts of the platen. Bearing screws 2' t i 13, working in tapped sockets in the plate a at different points, are brought to bear on the back of the platen after it is adjusted to the bed and hold the platen rigidly in the position to which it is adjusted.

The bed 0 works between suitable guides, and to its under side is pivoted a connectingrod, j, the lower end of which is provided with a slot, is, in which is a sliding box, I, which receives the wrist-pin of a crank, m, on a driving-shaft, it, said shaft being rotated by a suitable motor and raising the rod j and bed 0, when the sliding boxl in its upward movement strikes the upper end of the slot is, and allowing the bed to drop upon fi xed arrestingshoulders 0 when the box moves downwardly.

It will be seen that the provision of the slot is in the connecting-rod enables a crank to be used to operate the bed, the wrist-pin of the crank sliding in the slot of the connecting-rod after the downward movement of the bed is arrested, and affording time for the bed to be inked.

In practice the bed 0 will be provided with an electrotype-plate, the backing of which is held by dovetail guides formed in the bed.

The die-block d, on which the cutting-die acts, is rigidly affixed to the frame a. To the cutting-die is pivoted a connecting-rod, g, which connects said die with a crank, r, on a shaft, 8, journaled in hearings in the frame of the machine and rotated by a positive connection with the shaft 01, which operates the press bed. Said connection consists of a shaft, t, journaled in bearings at one side of the machine, with a bcvel-gear, u, meshing with a similar bevel-gear, r, on the shaft 02, and at its other end with a bevel-gear, a, meshing with a bevel-gear, b, on a shaft, 0, extending crosswise of the machine, (said shaft actuating a part of the inking mechanism, as hereinafter described) and a shaft, 0, journaled in bearings at one side of the machine, and provided at its ends with bevel-gears f 9, one meshing with the bevel-gear b on the shaft 0, and the other with a bevel-gear, h, on the shafts. The cranks of the shafts a s are so arranged that the bed 0 is pressed upwardly and the cuttingdie 0 is pressed downwardly against the paper simultaneously.

An intermittent feed mechanism is provided between the printing and cutting mechanisms, whereby the web of paper is moved forward only when the press-bed and cutting-die are retracted. Said feed mechanism is composed of two pairs of rolls, 1'. ijj', between which the web passes, the lower rolls, j, being on a positively-rotated arbor, 75, while the arbor l of the upper rolls isjournaled in sliding boxes,

U which are pressed downward by screws m, so

that the upper rolls are pressed against the web and rotated by friction.

The arbor L of the lower rolls is provided with a gear-wheel, a, which is connected with said arbor by a friction device, which permits the gear-wheel to rotate backwardly without rotating the arbor, but causes the gear-wheel and arbor to rotate together when the gearwheel is rotated in a forward direction, as indicated by the arrow in Fig. 1. In the present instance I have shown the friction device as a dog, 1), (see Fig. 4,) pivoted to the gearwheel a, and pressed by a spring, q, against the periphery of a disk or collar, 1*, rigidly attached to the arbor It. When the gear-wheel a is iotated in the forward direction above indicated, the dogp binds upon the disk 1' and rotates the arbor; but when the gear-wheel is rotated backwardly the dog slips and the arher is not rotated. Any other suitable or wellknown friction device may be used for this purpose.

The gear-wheel n is oscillated by means of a reciprocating rack, r, meshing with said wheel. The rack is adapted to slide in guide at, affixed to the frame a, and is reciproeated by a connecting-rod, a, connecting the rack with a head or arm, c. Said head or arm is provided with a slot, 20, in which is a screw, a", journaled in bearings, so that it will not move longitudinally when rotated.

On the screw a is a nut, If, which is prevented from rotating by contact with the sides of the slot 10, but is adapted to move along said slot. The connecting-rod u is pivoted to the nut I). It will be seen, therefore, that by adjusting the nut If toward or from the axial line of the shaft 3, any desired length of movement can be imparted to the rack 1", and through the latter any desired extent of feeding movement can be imparted to the rolls 2' j, so that the web may be iven a longer or shorter feed.

c 0 represent inking-tablcs affixed to the framea at opposite sides of the press-bed. d (1 represent distributing-rollers, which are provided with ink-feeding reservoirs c, and are moved back and forth along the tables 0 by means of connecting-rods f, connecting the yokes in which the rolls d are jourualed with arms g affixed to the arbor 0 above mentioned. Said arms are arranged reversely, so that the distributiug-rollers 11 d. are moved simultaneously in opposite directions, one being at the forward end of its table when the other is at the rear end of its table, as shown in Fig. 3.

In Fig. 5, h h? It represent a series of rolls which receive the ink from the tables 0 and apply it to the type on the bed. Said rolls are journaled in plates i i", which are connected by pivoted rods or links jjtvith a frame, k which is reciprocated crosswise of the frame a and in a direction at right angles with the length of the ink-tables 0', so as to move the rolls If back and forth across the bed and cause them to rest alternately on the table 0 at the right and the table 0 at the left of the machine. The frame of these rods is secured to a long bar or slide, 1', which is adapted to move in a suitable guide in the frame a, and is reeiproeated by means of an arm, a affixed to and rotated by an arbor, o", geared to and rotated by the crank-shaft n, which operates the press-bcd,an arm orlever, m pivoted at q" to a fixed bracket on the frame a, and links 1' r", connecting the upper and lower ends of the lever m respectively, with the bar Z of the roller-carrying frame and with the arm a". (See Fig. 8.) The retation of the arbor 0 oscillates the lever m and causes it to reciprocate the roller-carrying frame the movements thus imparted to said frame being sufficient to carry the rollers h from one table 0 across the bed and onto the other table 0'.

The operation as a whole is as follows: The web w having been introduced into the machine and grasped by the feed-rollers ij, the press-bed ascends and the cutting-die at the same moment descends, the web being thus simultaneously printed at one point and cut to form a blank at another point. The platen and cutting-die are then simultaneously retracted and the blank last out slides down the inclined bed and out of the machine by gravitation, and the feed-rolls are rotated and feed the web forward until a portion printed by the platen is in position to be cut by the cuttingdie a.

The feed-rolls may be regulated so that the portion of the web printed by the last action of the bed will be carried at one movement into position to be cut, or by more than one movement.

\Vhen the type-bed is fully depressed, it remains at rest before the crank again raises it,

and-while the type-bed is thus at rest the inking-rolls h 7L2 are moved off from the table 0 at one side of the machine across the type-bed, inking the type thereon, and onto the opposite table 0 The distributing-roll d of the table last vacated by the rolls If advances and inks said table while the rolls h are away from it, and retreats before the rolls return, so that each table is freshly inked between each departure and return of the rolls h". The operation is thus continued, the rolls passing across the type-bed first from one side of the machine and then from the other.

The portion of the web over the type-bed is kept taut and prevented from slipping forward bya pair of pressure-rolls, 16 a, between which the web passes.

The organized paper-box machine, consisting of the combination of the printing, feeding, and cutting mechanism, and the specific improvements in the feeding mechanism, constitute the subject of two separate applications for Letters Patent by me filed on the 9th day of October, 1885, having Serial Nos. 179,402 and 17 9,403.

I claim 1. The combination of the frame a, typebed a, inkingtables arranged in the same plane and upon opposite sides of said bed, distributing-rolls d d, and mechanism, substantially as described, for moving said rolls over .the inking-tables, and independent type-inking rolls, with mechanism, substantially as described, for moving them across the type-bed from one table to the other, substantially as described.

2. The combination of the frame a, the reciprocating type-bed c, inking-tables arranged in the same plane and upon opposite sides of the path of movement of said type-bed, distributing-rolls d (1 and mechanism, substantially as described, for moving them over said table for inking the same, and type-inking rolls, with mechanism, substantially as described, for moving them across the type-bed when stationary in the plane of the two inking-tables, substantially as set forth.
